To all whom itmay concern? Be it known that I, TRI BLE DIQRQODE, asubject of the Queen of the Netherlands,

residing in the borouglrofManhattan, city and county and State ofNewYork, have invented certain new'and useful Improvements in CombinedTy1)e-\/V1'iti11g.a11cl Printin g Machines; and I do herebydeclare thefollowing-to be a full, clear; and exact description of the invention,such aswill en-- letter and insert ng the Salutations in-the" severalcopies individually. i The ob ect of theinventmn is tOTJIOX'IClQ, a combned typewritlng and printing mechanism of this character wh ch issimple-inconstruction, vrhch may be manufactured at low cost, whichmaybe operatedby unskilled persons and with which circular letters maybe produced partly by aprinting operation and partly by a typewritingoperat'on with the typewritten and paintedportions having-the sameappearance and the appearance of-typewritten Work. A further ob ectof-the invention is to so construct the mechanism asto permit ofinsertmg not only the salutations, but also any other desired portionsof the circular letters by means otthe typewriting mechanism theconstruction being arranged to facilitate-ops eration of the typewritingmechanism to print the desired typewritten matter atthe proper points onthe sheet.

Inaccordance with the inventioma typewriting mechanism is provided withthe usual roller platen movable transversely of the machine and, in addtion thereto.; a sec- 0nd platen adapted to be used in'the printa ingoperation, and a support for a typeform consisting of a multiplicity ofindi-- vidually set-up type is arranged in position roller, effected bythe line-spacing mechanism of the machine, causes thepap'erto beforwarded over the surface of the second platen sothat a succession ofOPQl'ilt'lOllS'Of the line-spacing mechanism will moye the sheet ofpaper into the position required for printing thereon from the form oftype. Preferably, the platen for coaction with the type-form is flat andis arranged in avertical position immediately over the trontfof theroller platen of the typewriting machine. a In addition tothe twoplatens on the carriage of thetypewriting mechanism, rollers;-

are provided on the carriage,forsupporting;

the ends of an ink-r bbon which extends from one rollerraroundthe rollerplatenand then over the face ofthe fiat platen tothe other-roller;Thisink-ribbon supplies the ink for-printing :both from the key-levers.of'thetypewriter flHCl'fFOHl the type-form sothat the'bodv of theletters printed on the machine ancl the 'salutation printedby thetypewriting mechanism must necessarily be identical in color. -Also, anadjustable stop isprovidcd for limiting the pressure whichthe type-formmaybe caused toexertagainst the sheet'and the coactirg platenseas-tofurther fac'litate the production of letters which are identicalin appearance both as tothe body ofjthe letter printed froin thetype-form and the salutation'and other-parts printed with thetypewriter;

In order to aid the operator in positioning the sheet with' reference-totheplaten roller 1 when printing the salutation or' any other po tion ofthe letter wh ch-is to lie-printed with the typewriting mechan sm; aplurality of adjustable stops is provided wh ch may be positioned soasto arrest themoveinent' of the sheet around the platen roller.

Fig. 5 is a perspective view of one of the stops;

Fig. 6 is a perspective view of one of the type; and

Fig. 7 is an elevation of an impression V controlling device hereinafterdescribed.

Referring to these drawings, a typewriting mechanlsm of the usual or anysuitable construction is shown in Figs. 1 and 2, having a plurality ofkey-levers 7, operated by keys 8, in the usual manner.

The typewriter has a transversely movable carriage 9, adapted to moveunder the control of an escapement mechanism in the usual manner, itbeing supported upon rails 10. In the particular type of typewritingmechanism chosen for illustration, the shifting of the platen roller forprinting upper and lower case letters is effected by moving the carriage9 and all the parts mounted thereon in a vertical direction. For thispurpose, one of the rails 10 is mounted upon supports 11 which may bemoved upward by means of a shift-key 12. The platen roller 13 ismountedfor rotation in bearings formed upon the frame of the carriage 9 and itsposition is such that the type of thekey-levers 7 coact with the frontface of the roller 13. Two reels are shown at 14 for use in supportinga'narrow ink-ribbon which is adapted to extend between the arms of aguide 15 (Fig. 1). This ink-ribbon mechanism, however, is that which iscommonly employed with a typewriting mechanism of the constructionchosen for illustration, and

in adapting the machine for use in accordance withthe present invention,this'inkribbon mechanism is not employed.

The carriage 9 of the machine has a second platen mounted thereon inaddition to the roller platen 13 and these two platens together with theink-ribbon mechanism employed therewith are adapted to move togethertransversely of the machine under the control of the escapement. Thesecond platen is flat and is arranged in a vertical plane extendingupwardly from the front face of the roller platen 13. This flat platenis shown at 16; it consists of a sheet of hard rubber mounted upon ametallic base-plate 17. The plate 17 with the platen 16 affixed theretois secured to the frame of the carriage 9, as shown in Fig. 4', so thatit moves crosswise of the machine with the roller 13. The platen 16forms one member of a printing couple, the other member of whichconsists of a form of type located directly opposite the platen 16 upona supporting plate 18. This plate 18 has bearings 19 formed on the rearface thereof which bearings receive eccentrics 20 mounted upon shafts21, the plate 18 being adapted to slide upon the eccentrics 2Otransversely of the machine. The two shafts 21 are mounted in bearings22 secured to framemembers 23 rising from the base on which thetypewriter mechanism is mounted. At one side of the machine, the shafts21 extend through the bearings 22 and have. cranks 24 secured thereto.The outer ends of these cranks 24 are connected by a link 25 and thislink is pivotally connected to the upper end of a long lever 26. Thislever 26 is connected to an operating lover of any suitableconstruction; in the present case, the operating lever is shown at atreadle 27 pivoted upon the floor and provided with a suitablefoot-piece 28. An adjustable stop is preferably provided adapted tocoact with the lever 27 so as to limit the extent of its downwardmovement. Such an adjustable stop is shown at 29 in Fig. 2, it beingmounted upon the floor under the support for the machine.

The type of the type-form are preferably of the construction shown at 66in F 6. For the support of these type, a plate 30 is provided having aplurality of under-cut grooves extending across the face of the plate inparallel relation as shown in Fig.

,4. The type are individually assembled upon this plate 30 by movingthem lengthwise into the grooves in the plate, the lines of type beingheld in proper position in their grooves by any of the well known means.The plate 30 may be provided with lugs or rails 31 adapted to bereceived in transverse grooves in the supporting plate 18 so that theplate 30 with the form of type thereon may be readily mounted inposition and withdrawn when desired.

For the purpose of guiding the platen 16 in its transverse movement, abar 32 is preferably provided extending between the frame-members 23immediately in the rear of the plate 17. The front and rear faces ofthis bar are accurately finished and brackets 33 are secured to theplate 16 and extend in rear of the bar 32. These brackets are so spacedapart as to permit of a limited extent of vertical movement of the plate17 and the platen thereon. such movement beins effected by the shift-key12 heretofore referred to.

The transversely movable carriage also supports the ink-ribbonmechanism. This mechanism consists of a single ribbon of substantialwidth which extends around the estates platen roller 13 and over theface of the flat platen 16. The ends of this ribbon are carried uponsuitable rollers and one or both of these rollers is provided withmechanism for effecting the feeding of the ribbon. In Fig. i, a rolleris shown at 34 mounted upon the frame of the carriage 9 to the rear ofthe platen roller 13. The ribbon 35 extends from this roller 34: betweena pair of guides, and around the platen roller 13. These two guides, 36and 37, are plates of thin sheet metal secured to the frame 9 of thecarriage and having their forward ends curved so as to be concentricwith the roller 13. Between the two plates is a narrow space throughwhich the ribbon 35 passes and between the plate 36. and the roller 13is a narrow space through which the sheet of paperpasses. The two plates36 and 37 terminate on the front side of the roller 13 immediately belowthe striking point of key-levers of the typewriter. The forward edge ofthe plate 36 is serrated and the fingers thus formed on the edge of theplate are bent inwardly as shown at 38 in Fig. 4:. These fingers pressthe sheet of paper against the roller 13 and thus insure feedingmovement of the sheet as the platen roller 13 is turned and also holdthe sheet against displacement when the type-form is operated. Theribbon 35 passes vertically upward from the roller 13 between the platen16 and the type-form and at its upper end is wound upon a roller 39.

' This roller i journaled in brackets extend" til ing upwardly from theplate 17. On one end of the roller is a ratchet wheel4l0 (Fig. 2)engaged by a pawl 41, pivoted on a pawlcarrying arm 42. This arm isloose on one of the trunnions of the roller 39 and is moved in onedirection by a spring 43 and in the opposite direction by a stop 44secured upon the front face of the supporting plate 18. When the plate18 is moved to carry the type-form into coaction with the platen,itsmovement causes the arm 12 to be turned against the tension of spring43, so that pawl 41 will turn the ratchet and the roller 39 a distanceequal to one tooth of the ratchet.

Each machine is provided with. a plurality of stops which may be of theconstruction shown in Fig. 5. Each of these stops has a part -fl5adapted to fit into the end of a groove in the plate 30, and a transversely disposed part 46 whose end extends into the path of movement ofthe sheet of paper to be printed upon. The several stops for a machinemay be different as to the length of the portions 46 thereof. When astop such as that shown in Fig. 5 is seated in the end of a groove inthe plate 30, as shown'at 47 in Fig. 2, the movement of a sheet of papereffected by the line-spacing mechanism of the typewriter will carry theedge of'the sheet into-engagement with the stop. The stop will thenarrest further movement of the sheet or the sheet will become bowed ifthe line-spacing mechanism is again actuated. In preparing the machinefor use, the operator may place a stop in such position that it will beengaged by a sheet when the sheet is in position for type vriting thesalutation. 01:, several stops may be arranged in position for arrestingthe sheet at several positions corresponding to the positions wheretypewritten matter is to be inserted. In order to permit of moving asheet beyond the position in which it coacts with the stop, a strip 4:8is provided at one edge of the plate 18. This strip is carried by armsas which are pivotally mounted upon the top and bottom of the plate 18.The'strip has a plurality of slots cut in its edge of a width slightlygreater than that of the portions 46 of the stops and the fingers formedby the provision of these slots are bent inwardly as shown in Fig. 3.Secured to or formed integral with the lower arm 49 is a lever 50. Bymoving this lever, the several fingers of the strip 48 may be movedforward so as to engage a sheet which has been arrested by a stop andmove the edge of the sheet with the fingers until. it is carried beyondthe end. of the stop. The slots in the strip 48 permit the strip to passover any stops which have been positioned in the type-channels The sheetmay then be moved upward to a further extent by operation of theline-spacing mechanism.

It may occur sometimes that when a sheet has reached such position thatits edge is in contact with a stop and the operator is writing with thetypewriting mechanism, it will be necessary to shift the carriagevertirally for printing an upper case letter. In order that shifting ofthe carriage at such time may not cause bowing of the sheet due to itscoaction with the stop, I provide means for efiecting the automaticactuation of the comb-plate 418 by the carriage-shift ing mechanism. Forthis purpose, the frame of the carriage has a lever 51 (Fig. 2) securedthereto having a cam surface 52 which normally lies under and in frontof the lever 50. When the carriage is raised vertically by operation ofthe shift-key, this cam surface acts on the lever so as to cause it tomove in the direction for actuat ting the comb-plate 4:8 in the mannerabove described.

The ends of the shaft of roller 13 are received in depressions in .theframe of carriage 9 shown in Fig. 2 and are held therein by strips 58which may be moved out of the way by handles 59 thereon. When thusmoved, the platen roller, the flat platen 16., the ribbon mechanism, andthe parts as? sociated therewith may be raised out of coaction with thetypewrltmg machine:

Theplaten roller 13 is prorvided Withthc Ill) and knob 54:simultaneously with one hand,

such simultaneous operation being desirable when the sheet of paper isin contact with a stop and it is desired toeffect a line-spacingmovement of the sheet. An impression controlling device for thetype-written matter is shown in Figs. 1 and 7 This consists of a springmetal piece 55 secured to the ribbon guiding device 15 and arranged tobe struck by each of the key-levers 7 just as the latter is brought tothe position for striking the sheet. This piece is shown in Figs. 1 and7 as mounted on the guide 15 for the ink-ribbon of the typewritingmachine. This guide is provided with a screw 56. To position the piece55, this screw is loosened and the fingers 57 of the piece 55 are passedover it. These fingers are bent inwardly as shown in Fig. 7 so that theybear against the guide 15 and the screw 56 mav be tightened up such anamount as will hold the piece 55 in the desired position. The upper endof piece 55 presents two diverging arms and a curved edgebetween them.The upper end of each key-lever will strike this upper end of the piece55 at a point on the key-lever near the type thereon. By adjusting theposition of piece 55 with screw 56, the strength of the blows of thekey-levers upon the sheet may be decreased to any desired extent. Thisimpression controlling device aids materially in the production ofprinted and typewritten letters which are the same in appearance overall parts thereof, particularly, when the typewriting is done by. anoperator who strikes the keys with considerable force and who. withoutthe use of the impression controlling piece would print the typewrittenmatter with a heavier impression than it would be desirable to obtainwhen printing from the typeforms The operation of the mechanism thusconstructed will now be described. The body of a letter is set up bysuitably arranging type in the Channels in the plate 30. If desired, thetype-form may be arranged to print the entire letter except for thesalutation. or spaces mav be left at various points in which any desiredwords may be inserted by typewriting. This having been done,

' the plate 30 is positioned upon the supporting plate 18 by arrangingit at one side of the plate 18 and then moving it laterally sothat thelugs or rails 31 enter the grooves '1 provided in the plate 18. The edgeof a sheet of paper is then inserted between the rear face of the platenroller 13 and the guide-piece 36, and the roller 13 is then rotated tocarry the sheet around the roller until its edge projects beyond theedge of the fingers 38. A stop such as that shown in Fig. 5 is placed inthe end of a channel of the plate 30 in such position that it will beengaged by the edge of the sheet when the sheet is in the position forreceiving the salutation or other matter to be written with thetypewriting mechanism. The roller 13 is then turned until the edge ofthe sheet engages this stop whereupon the typewriting mechanism isoperated in the usual manner to print the salutation. This having beendone, the operator manipulates the lever 50 so as to cause the edge ofthe sheet to be disengaged from the stop and at the same time turns theplaten roller 13. If no other matter is to be typewritten, the roller 13is turned so as to carry the sheet upwardly between the ribbon 35 andthe platen 16 until the proper position of the sheet with respect to thetype-form is shown by the engagement of the edge of the sheet withanother stop positioned in a higher channel of the plate 30. The sheetwill still be held against acc dental displacement by the fingers 38.which. throughout the operat on above describ"d are in eng gement withthe sheet. At this time or before moving the sheet upwardlv. thecarriage is moved to a predetermined position with reference to thecoacting scale on the frame of the typewriter so that the sheet will bein proper position for printing with reference to the typeform. Theoperator then presses the operat ng lever 27, thus rocki g the shafts 21in their bearings and when the shafts are so rocked. the eccentricsthereon cause the plate 18 and the tvpe-form supported thereby to movetoward the platen 16 so that the printing faces of the type in thetype-form engage the sheet through the inking ribbon with the desireddegree of pres ure. On release of the lever 97. a. spring 65 returns itto its normal position thus retracting the ty e-form and the operatormav then turn roller 13 until the unncr edge of the sheet is carriedabove the platen 16 far eno gh to permit of grasning'it and withd awingit from between the type-form and the platen. The support for thetype-form a d the tynewriting mechanism are so positioned relativelythat a word printed on a sheet with the tvpewriting mechanism will alineaccurately with words print d from the t peform intended to be read inthe same l ne with the typewritten word or words. This makes it possibleto have one or more words of a line in the body of a letter typewrittenwhile the other words in the same line are printed without thedifi'erence in the method employed appearing on inspection of theletter.

It will be seen that in this way multiple copies of a letter may beprinted from a menses type-form. and on each one of the copies anindividual salutation may be written with the typewriting mechanism.These two printing operations are effected with the same ink-ribbon sothat objectionable differences in the appearance of the completed mattersuch as are almost invariably present when part of the printing is donewith one ribbon and the remainder with another are avoided. It will benoted also that there is no restriction as to the location of thetypewritten matter with respect to the matter printed from thetype-form; not only may the salutation be written in with thetypewriter, but also any other part or parts of the complete letter maybe typewritten. This requires merely that suitable spaces be providedwhen setting up the form of type and the positioning of stops to aid theoperator in typewriting at the points corresponding to these spaces. a rr The provision of an adjustable stop for arresting the movement of themechanism for printing from the type-form is important in that it limitsthe degree of pressure of the type-form upon the sheet; in this Way, itis possible to guard against having some of the letters printed from thetype form much heavier than others as a result of which difierences inthe appearance of the body and Salutation of the letters would appear,at least upon some of the copies,
